WINDOW-WASHING DEVICE.k

Application fiiea December 1o, 192e.

My invention relates to window washing devices and more particularly to a device adapted to wash windows in office buildings and .similar structures.

Vindows in such buildings are customarily washed by` hand, necessitating the window washer climbingonto the outside sill andl holding himself in place by means of a safety belt secured to the window frame. While this method of washing windows produces vei'y satisfactory results, it is highly dangerous and oftentimes the window wash- Ver falls to'his death through a 'misstep vor 4the Vby a window washerwhile standing on the outer sill.

These and vai'ious otherobject-s and advantages will bevmore readily understood from the following description and from the accompanying drawings in which Fig. 1 is an outside view of a window t which my device has been attached,

Referring now moie in detail lto the draw- 6o ings, the deyice is shown mounted on a window having-an upper sash 15, a lower sash 16,

jambs 17 and 17 a, and a sill 18. y vA rod` 19 is clamped to the ends of the inner edge of the sill by means of suitable clamps 2O and has a guide 2l mounted thereon and slidable the entire length of the rod. A base structure 22 is hinged to guide 21 and extends outwardly through the window open ing, ending in a hollow frame 23 which is 70 supported by a roller 24 adapted to contact with the outer sill of the window. l

A pair of rods 25 aresecured to frame23 and extend upwardly therefrom. A carriage 26 is slidablymounted on rods 25 and has a 75 shaft 27 `extending transversely thereof, on one eiidof which a holder 28 is rigidly se# cured and which is adapted to carry a squeegee 29,701" a sponge. A sheave wheel 30vis rigidly secured to the other endv of shaft A27 80 which is'held against outward movement by y means of a collar 31 secured to the shaft on Y the inside of carriage 26. The function ofk v these parts, together with other details, will be later described. In order to support the upper end of my device, a hook 32 is fastenedinto window jamb 17, about midway of its height, and an eye 33 secured to amb 17aN directly opposite. A

rod-34, having an eye in one end,-by means of which it engageshook 32, extends toward the Vcenter of the window and a rod-35, terminatingl in a snap-hook 36 (Fig. 12) by means of which it is secured to eye 33, extends inwardly from jamb 17 a with the ends of rods 35 and 34 95 spaced a short distance apart and surrounded by a tubular member 37 which holds the two 'rods inalignment and with them forms the support for the upper end of the device.

A hanger 38. is mounted on member 37 by 100 means of a pair of ball bearings 39 (see Fig.

V11).which allow hanger 38 to moveffreely on member 37. The lower end ofhanger 38 is bent inwardly, terminating in a support 40-v to which are connected the upper ends of rods 105 25. Connected also to support 40are a pair v `of struts 41 from the outer endV of which a pair of vertical braces 42 extend downwardly and connect to hollow frame 23. The braces 42 are tied together by means of one or more cross braces 43, asshown in Figs. 1 and 2.

A support 44 is secured near the upper ends of braces 42 and rods 25 and is adapted to rotatably support a sheave 45, approximately in the saine plane with rods 25, and a shcave 46, approximately in the plane with braces A shaft 47 is iotatably mounted in base structure 22 and frame 23 and has its inner end bent to term a handle 48 by which it may be manually rotated. The portion of shat't 47 disposed within frame 23 carries a liXed sheave 49,11 loose sheave 50, and a iXed collar 51 which is provided with projections 52. A lever 53 is mounted parallel to shaft 47 and has an oiset 54, whereby it may vclear sheave 49, and a forli 55 on the outer end of the olfset adapted to engage sheave 50 and force same into engagement with the Lprojections 52 on collar 51 so that, when so engaged, rotation of shaft 47 will cause rotation of loose sheave 50.

Acable 56 has one lend connected to carf' riage 26, whence it passes upwardly and over sheave 45, then downwardly and under sheave l4.9, then` upwardly and has its other end con- 47 will cause cable 56, and consequently carf riage 26', to move upwardly or downwardly.

' At either side ot shaft 27 a pair of lugs 57 extend inwardly and are adapted to prevent rotation of shaft 27 more than 45"O in either direction by making contact with a pin 58 extending vertically from the shaft. A pair of grooves 59 are rformed at right angles to one another in the hub of holder 28 and a round headed pin 60 is inserted in the carriage 26, so that the head of pin 69 is adapted to engage one Vof the grooves 59, when squeegee 29 is heldhori'zontally by holder 28,` and to engage the other groove when the squecgee is vertical.

Referring now more particularly to Fig. 1, 6 and-'7, it will be seen'that an endless cable 61 connects shea-vo 30 with loose sheave 50 and upper sheave' 46, with one side of the cableV making one or more turns around slieave 3() on shaft 27. As previously explained, orcing leerer 5'3 outwardly will bring sheavel) intoenga gement with projections 52 on collar 51 so that, by rotating shaft 47, cable 61 will rotate sheave 30 a quarter-turn in either direction when further movement is prevented by lugs 57 and pin 58 and the squeegee held in this position by the head of pin l6() entering groove 59. Holder 28, being normally held in position by the spring action of squeegee 29 holding groove 59 in engagement with the head of pin 60, a slight effort is necessary to start rotation as this arrangement acts in the y saine manner as a spring ball catch.

In order that the device maybe readily moved from side to side of the Window, a hand grip 62 is clamped to the upper side of base structure 22 and a roller bearing 63 clamped to its underside beneath the hand grip. A spherical roller 64 is mounted for universal rotation in bearing 63 and is adapted to engage sill 18 and support the inner end of base structure 22., as plainly shown in been placed in the window jambe approxi! mately midway o t their height, the device would be operated as follows: i

`Vlh'e lower sash is raised, rods 34 andV 35'.

secured to hook V32 and eye 33, and the bottom of .the device swung outwardly so that roller 24 will rest on the outer sill. Clamps 20, carrying rod 19, are next clamped to the corners of the inner sill, a wet sponge inserted in the holder 28, and both sashes lowered until their bottoms nearly engage base structure 22.

The'dcvice isV then drawn inwardly untilv the sponge comes in 4contact with the glass of the upper sash, shait 47 rotated to raise holder 28 to the top oi the glass, thederice moved 9o from side to side of the window,,by'grasping handles 48 and 62, and the sponge gradually lowered .by turning` handle 48 until the einy tire surface ot the window has been ,waslrd The device is then moved outwardly, a Vsqueegee substituted for the sponge aud handle 48V turned to bring the squeegee to its uppermost position.

In case the windows hook '32 and eye `33cannot be so located that squeegee 29 may engage the very uppermost part ot the glass while in a herir/.ontalposition, lever 53 is shoved youtwardly so as to iii: shearc 50 to shaft 47 and handle 48 ro'- are of such size that.

tated to turn squeegee 29 in a if'ertical posi- 105 tion; after which lever 53 is withdrawn and the squcegee brought'to the proper height and moved across the glass, it may then beY returnee to a horizontal l'iosition and the window dried by drawing the squeegee dofwnwardly by the rotation of shaft 47 as previously described.

After the upper sash has been wa-shed'and dried, it is raised to its uppermost position andthe process repeated with. the outer side of the lower sash. lt is evident that, when in its upper position, the bottom of the upper sash will overlap the top ot the bottom sash y due to vsaine being` slightly raisedv to allowY izo ing the lower sash, the lower part of hanger 38 willreach under the bottoni'of the upper sash with a minimum lesstof headroom. I

VThe arrangement shown in Figure 8 is identical with .the arrangement shown in the v other figures with the exception that rod l),

j ably supported on a hanger G6, the upperl end .of which is secured to a bearing 67 clamped on base structure 22 and forming the inner bearing for shaft 47.
